A top global health agency has declared the main ingredient in medical cannabis non-addictive and nontoxic, according to a new report.

“In humans, CBD exhibits no effects indicative of any abuse or dependence potential,” the World Health Organization, a United Nations agency that focuses on public health, wrote. Researchers spent months looking into cannabidiol (CBD), the non-psychoactive ingredient in marijuana that’s often used for medical purposes. It often comes in the form of oils, drops or capsules.
